In a bolted fault there is a solid connection. This allows the fault current to flow through a conductor. This type of fault might happen when an installer connects to a power source to ground instead of to the point where it should be connected. When the power is switched on there will...
The transformer, as the hub of power systems, its health status directly impacts the stability and reliability of the electrical system's operation. Therefore, the precise management of a transformer's health status is paramount to ensuring the steadfast and secure operation of the power grid1. ...
The proposed power transformer fault diagnosis method DIL-DS, based on DGA and the improved LightGBM hybrid integrated model with a dual-branch structure, can be mainly divided into the following par...
For the modeling of user feedback sequences, there are many algorithm schemes in the industry, such as the well-known DIN (Deep Interest Network[10]), DIEN (Deep Interest Evolved Network[11]) and Transformer-based BST (Behavior Sequence Transformer)[12]) and so on. In the on-device sort...
The paper presents a fault region identification method for the active distribution network (ADN) with limited PMU. First, PMU configuration and region division strategies are proposed based on the network topology. Next, the difference in three-phase cu
A new high-frequency-based method for the very fast differential protection of power transformers the amplitude of the transformer differential currents, it is needed to know if the over-current is because of an internal fault or an inrush phenomenon... S Hasheminejad - 《Electric Power Systems...
The authors describe experimental and theoretical analyses of faults of power transformer winding. Faults were caused by mechanical effect of short-circuit... J Zaytoon 被引量: 0发表: 2017年 Vehicle fault diagnosis system and related methods of cooperative multi-agent formula Vehicle fault diagnosis ...
voltage of its own terminal electric point which will be generated at the ground-fault in one line and zero-phase current flowing through circuits in a system in which a transformer at the end of an opponent bus in a parallel multi-circuit power transmission line having a mid-point impedance...
The conventional model-free predictive current command (MFPCC) strategy of DFIG introduces high ripples for constant power and current harmonics, which is undesirable. This control uses only eight fundamental voltage vectors for a two-level transformer, causing distortion of the rotor and stator curren...
In the context of global energy transformation, the construction of smart grids is becoming a novel vogue in the evolution of power systems. As the core node of the smart grid, the efficient operation of the intelligent substation relay protection system
